Abstract
Formation of holographic polymer-dispersed liquid crystal (HPDLC) memory for an optically reconfigurable gate array based on the angle-multiplexing recording is discussed by controlling the laser interference exposure in liquid crystal (LC) composites. The successive laser illumination system to record the various configuration contexts at the different region and angle in HPDLC memory is constructed by using the half mirror and photomask placed on the motorized stages under the control of a personal computer (PC). The effect of laser exposure energy on the formation of holographic memory is investigated by the measurement of diffraction intensity during the grating formation process. The reconstruction of configuration contexts for the various logical circuits is demonstrated by the laser illumination at different incident angle in the HPDLC memory.
